> A hand-written parser can have better error recovery and more helpful error messages. That depends on what you're comparing to. The Menhir parser generator can generate a file with all possible "error states" in the parser in which you can specify very nice and friendly error messages for each one. I've posted this before: http://gallium.inria.fr/~fpottier/slides/fpottier-2015-11-ou... (ignore the French title, the rest is in English). The examples for a C grammar in Menhir show much better error messages than the hand-written GCC ones. |
